pnp4nagios not working since core 4 upgrade

Hey,
Was using Nagios Core 3.5 for over 12 months along with pnp4nagios 0.6.21 I think in sync mode. All was working fine until last week I upgraded Nagios Core to 4.0.8. The upgrade went fine but today I noticed pnp4nagios although it looks to be working and shows me historical data, isn't recording any new info?

I downloaded the verify script and this is what I get.

Code: Select all

Now all my paths look OK and like I say, pnp4nagios can see historical data like the monthtly/yearly graphs and let me drill down OK, its just new data coming in. One thing that jumps out at me from the verify script is:-

Code: Select all

[WARN]  Perl RRDs modules are not loadable
Not sure why this came up, so I did a yum install rrdtool-perl and now this clears OK but still doesn;t work?

I'm thinking it might be soemthing to do with

Code: Select all

[WARN]  166 hosts/services are not providing performance data
[WARN]  'process_perf_data 1' is set for 167 hosts/services which are not providing performance data!
so assume this is a change the 4.0.8 upgrade did to my config files? Any suggestions?
Thanks!

OK, fixed this myself.

Turns out the problem was that pnp4nagios doesn't work in syncronous mode with nagios core 4.x. I found a load of errors in my Nagios event log relating to the service perfdata worker failing. Then I found this entry on another forum - http://www.monitoring-portal.org/wbb/in ... adID=29625 where someone had the same problem, and was able to resolve it by changing from sync to bulk+npcd. Once I did that the graphs have started working again and my event log is much happier!

Hope this helps someone else :)
